Abstract: 1. A remote-controllable device for thermal treatment of cooking vessels which operate with overpressure, comprising: a remote control (3) with a transmitting device, a receiving device (13, 47, 48, 49), said receiving device being located on the remote-controllable device and being allocated to the transmitting device, an actuator (14, 50) which is connected to the receiving device (13, 47, 48, 49), and a power supply unit (15, 56) by which means the receiving device and the actuator are supplied, said actuator (14, 50) actuates at least one control member (8, 40) for releasing an opening (44) of the cooking vessel. 2. The remote-controllable device of claim 1, wherein the remote control (3) and/or the receiving device comprise(s) a timing unit. 3. The remote-controllable device of claim 1 or 2, wherein infrared rays, radio signals or ultrasound are used for transmitting signals between the transmitting and the receiving devices. 4. The remote-controllable device of claim 1, 2 or 3, wherein said control member (8, 40) actuated by the actuator (14, 50) is a part of a steam releasing valve. 5. The remote-controllable device of claim 1, 2, 3 or 4, wherein a two-way transmitting/receiving devices are mounted each in a remote control board (3) and in the remote controllable device, said remote control board (3) is provided with an indicator (22) of pressure and/or temperature ratio. 6. The remote-controllable device of claim 5, wherein said indicating device (22) comprises alarm signal device for indicating an abnormal regime of operation. 7. The remote-controllable device of claim 5 or 6, wherein said indicating device comprises a device (27) of speech output. 8. The remote-controllable device of any preceding claim, wherein said control member comprises a drive motor with a reduction gear (14) and a worm gear (16, 17). 9. The remote-controllable device of claim 8, wherein said drive motor (14) comprises a conic element (30) with a lateral support surface, said element movable axially. 10. The remote-controllable device of claim 8, wherein said drive motor (14) comprises a deflecting lever (18) designed enabling to deflect via an eccentric worm gear. 11. The remote-controllable device of any preceding claim, wherein it as a housing (1) mounted between the handles of a corresponding cooking vessel. 12. The remote-controllable device of claim 8, wherein said housing (1) is provided with a sealed bayonet lock (58) mounted tightly on the cooking vessel, in particular, in its port (59). 13. The remote-controllable device of one of the preceding claim 1 to 10, wherein the housing is provided with a circular holder, fixed beneath the shoulder of the safety valve lining. 14. The remote-controllable device of any preceding claim, wherein an antenna (13) of the transmitting/receiving device is formed or completed by connecting to the metal parts (2) of the cooking vessel. 15. The remote-controllable device of any preceding claim, wherein it has a switching device for saving power of the power supply unit (15, 56). 16. The remote-controllable device of claim 15, wherein said corresponding receiving device actuates only for short period of time within a considerably greater time interval and more continuos operation is performed only at receiving signals of a corresponding transmitter. 17. The remote-controllable device of any preceding claim, wherein comprises a temperature and/or pressure pickup to determine a corresponding regimes in the cooking vessel or associated with it regimes. 18. The remote-controllable device of one of the preceding claim 1 to 10, wherein the regimes taken by the pickups are processed in the remote controllable device and/or in the remote control board (3) and are used for switching on/off of the remote controllable device and/or for actuating said driving motor. 19. The remote-controllable device of any preceding claim, wherein the steam releasing valve is rigidly fixed to the housing of the remote controllable device. 20. A lid of the remote controllable device, wherein said remote controllable device is mounted on it of any of the preceding claim. 21. The cooking vessel, wherein comprises  a remote controllable device of one of the preceding claim 1 to 18.
